It's easy to overshop and buy too much food at the grocery store. Inevitably, that food ends up going to waste, and subsequently you end up wasting money. If this happens to a lot, health blog Greatist suggests keeping a log of your wasted food for a week.

The goal here is two-fold. First off, you can get an idea of what you're actually eating so you can shop accordingly. Second, you track how much you eat and your behavior so you know when it's better to freeze a meal:

Designate a week in which you write down everything you throw out on a regular basis. Tossing half a loaf of bread each week? Maybe it's time to start freezing half that loaf the moment you buy it so it doesn't go stale before you're able to eat it.

Wasting food is easy enough to fight against, but you have to know what you really use. Keeping a log for a week or two is one way simple way to track that. Head over to Greatist for a few more tips on cutting down on food waste.
